The problem of liens on Bitcoin

The Problem of Liens on Bitcoin→

Fascinating.

Indeed, given the high volume of fraud and default in the bitcoin network, chances are most bitcoins have competing claims over them by now. Put another way, there are probably more people with legitimate claims over bitcoins than there are bitcoins [emphasis added]. And if they can prove the trail, they can make a legal case for reclamation.

This contrasts considerably with government cash. In the eyes of the UCC code, cash doesn’t take its claim history with it upon transfer. To the contrary, anyone who acquires cash starts off with a clean slate as far as previous claims are concerned. It is assumed, basically, that previous claims on cash are untraceable throughout the system. Though, liens it must be stressed can still be exercised over bank accounts or people.

How to Recover the Lost Art of Dying Well

by Matt

This post is a beautiful remembrance of a friend and moving meditation on suffering, life, and death.

In our efforts to terminate suffering — too often we can be forced to terminate the sufferer — when we were meant to liberate the aloneness of the sufferer, by choosing to participate in the sufferings — choosing to stand with the suffering, stay with the suffering, let the suffering be shaped into meaning that transcends the suffering.

The staggering truth is: Suffering is never a meaningless waste of your life, but a meaningful way through your life.Suffering is never a meaningless waste of your life, but a meaningful way through your life.

Sometimes the most painful chapters of our lives —- are the most meaningful chapters of our lives.

Suffering doesn’t have to destroy our ultimate life purpose, but can ultimately achieve our purpose in life.

Lee Kwan Yew

Lee Kwan Yew→

A visionary, a statesman. RIP.

ONE of the world’s great economic success stories, Singapore owes much of its prosperity to a record of honest and pragmatic government, the legacy of Lee Kuan Yew, who has died aged 91. He retired as prime minister in 1990 but his influence shaped government policy until his death, and will continue to do so beyond. Born when Singapore was a British colony, the young Mr Lee saw the humiliation of the colonial power by Japan and the tough years of Japanese occupation. A brilliant scholar, he thrived in London and Cambridge after the war and came back to Singapore to assume a leading role in the anti-colonial struggle, co-founding the People’s Action Party (PAP), which governs Singapore to this day. Mr Lee was its leader, and Singapore’s prime minister, when it won self-government from Britain in 1959. He led Singapore into merger with Malaysia in 1963 and, after their divorce in 1965, as a small, fragile independent nation. Singapore’s prosperity and orderliness won admirers East and West, and came to be viewed as a kind of model.

Apple’s Haptic Engine Enables Rich Touch UI’s

Apple’s Haptic Engine Enables Rich Touch UI’s→

One under appreciated feature of Apple’s Watch and new Macbook (both announced at Apple’s recent event), is the haptic engine embedded in both which provides feedback through precise vibrations. The range of sensations this haptic engine can generate just may enable a new generation of touchable user interfaces.

Could this very simple and very clever electromagnetic motor produce effects other than a fake click? “Most definitely,” Hayward says. In theory, the trackpad should be capable of yielding all sorts of illusions—clicks, indentations, holes, bumps, and other types of bas relief-like textures.

Apple showed its eagerness to explore this potential earlier this week, with an incremental upgrade to iMovie that adds haptic feedback for a handful of interactions. As explained in the release notes, “When dragging a video clip to its maximum length, you’ll get feedback letting you know you’ve hit the end of the clip. Add a title and you’ll get feedback as the title snaps into position at the beginning or end of a clip. Subtle feedback is also provided with the alignment guides that appear in the Viewer when cropping clips.”

The NFL Math Whiz on Why He Still Plays Football

The NFL Math Whiz on Why He Still Plays Football→

With all the talk about the incidence of head injuries in the NFL, it’s becoming more and more common to ask why NFL athletes continue to play the game. For the glory? For the money? But how much glory and money does it take to justify losing not just one’s health, but one’s mind?

Increasingly, it’s easy to think that the main reason NFL players continue to play the game is because they have no other options. And while that may be true of many players, it certainly isn’t true of John Urschel, an offensive lineman for the Baltimore Ravens, who holds a master’s degree in math who publishes his ongoing math research in professional journals:

Naturally, I believe that I have a certain insight into this dilemma, due to my non-athletic pursuits. In particular, I have a Bachelor’s and Master’s in mathematics, all with a 4.0, and numerous published papers in major mathematical journals. I am a mathematical researcher in my spare time, continuing to do research in the areas of numerical linear algebra, multigrid methods, spectral graph theory and machine learning. I’m also an avid chess player, and I have aspirations of eventually being a titled player one day.

It is a simple truth. Playing a hitting position in the NFL can’t possibly help your long-term mental health.

With all of these interests outside of the sport, I am often asked why I play football, how I feel about brain injury, and if that’s something I think about…

Self-Driving Teslas Coming by Summer?

Self-Driving Teslas Coming by Summer?→

This is amazing if true:

That became clear on Thursday, when Elon Musk offered a classic example of what journalists call “burying the lede.” He had called a press conference on the subject of a Tesla software update…

After he’d dispensed with that subject, Musk dropped in a casual addendum: all Teslas will get an over-the-air update this summer, probably around June, allowing them to drive in “Autopilot” mode.

The enigmatic, soft-spoken CEO didn’t offer many details, but it seems Autopilot will be disabled when you’re not doing freeway driving, which is by far the easiest aspect of autonomous vehicle activity. Musk did confirm that the Autopilot mode would be “technically capable of driving from parking lot to parking lot.” The car will also be allowed to drive itself when you summon it, and when you’re parking it in your garage.

Behind the Scenes of Apple’s ResearchKit

Behind the Scenes of Apple’s ResearchKit→

This is a fun story.

He was closer than he thought. Sitting in the audience that day was Mike O’Reilly, a newly minted vice president for medical technologies at Apple. A few months earlier, Apple had poached O’Reilly from Masimo, a Bay Area-based sensor company that developed portable iPhone-compatible health trackers. Now, he was interested in building something else, something that had the potential to implement Friend’s vision of a patient-centered, medical research utopia and radically change the way clinical studies were done.

After Friend’s talk, O’Reilly approached the doctor, and, in typical tight-lipped Apple fashion, said: “I can’t tell you where I work, and I can’t tell you what I do, but I need to talk to you,” Friend recalls.
